Gears are often needed in the movement or work of mechanical equipment. Gears are components that transmit motion and power. They are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque. In the process of gear processing and forming, it is often necessary to use a grinding device to grind the side of the gear.

A Chinese patent with publication number CN117620319A discloses a gear processing and forming device, including a workbench, a support is arranged on the workbench, a dust suction mechanism is arranged in the support, and dust suction operation is performed by the dust suction mechanism. A first electric cylinder is arranged on one side of the support, a transmission box is arranged at the push-out end of the first electric cylinder, a positioning shaft is assembled at the bottom of the transmission box, and gears of different sizes can be assembled in the positioning shaft. The bottom of the positioning shaft is fixedly connected by a three-jaw chuck, and the bottom of the three-jaw chuck is connected to a rotating seat. Symmetrical second electric telescopic rods are arranged on both sides of the rotating seat, and the top of the second electric telescopic rod is connected with a forming mechanism; when working, the gear part is assembled on the positioning shaft, and the height of the dust collector is adjusted according to the actual processed gear to ensure that the dust collector can completely absorb dust. At the same time, the first electric cylinder is used to drive the positioning block to descend and press the positioning shaft, and the bottom is fixed and positioned by the three-jaw chuck, and then bidirectional cutting operation can be performed to ensure the simultaneous positioning of multiple gears.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

As shown in FIGS. 1 to 10 , a gear processing device according to an embodiment of the present invention includes:

A cutting device body 36 disposed above the annular baffle 2;

A groove 51 is provided on the top of the workbench 1;

A limiting mechanism disposed inside the groove 51;

The limiting mechanism includes an inner gear ring 5 rotatably connected to the inner wall of the groove 51 through a bearing; the bottom inner wall of the groove 51 is rotatably connected with four tooth columns 53 through a rotating shaft; the four tooth columns 53 are circumferentially arranged inside the groove 51; the four tooth columns 53 are all meshed with the inner gear ring 5; a rack 52 is provided on one side of the four tooth columns 53; the racks 52 are respectively meshed with adjacent tooth columns 53; a driving mechanism is provided at the bottom of two opposite racks 52; a limiting opening 55 is provided on the other two opposite racks 52; two limiting blocks are slidably connected in the limiting opening 55; the top end of the rack 52 close to the center of the groove 51 is fixedly connected to the limiting column 54; the outer side of the four limiting columns 54 is sleeved with a gear blank 43; the cutting equipment body 36 is used to process the gear blank 43.

When different gear blanks 43 are processed, the apertures of the inner holes are different. The same gear blank 43 is used in different accessories, and the apertures of the inner holes may also be different. Inner holes of different sizes may not be directly assembled with the positioning shaft. When the limiting mechanism provided by the present invention is used, the gear blank 43 is first placed on the support seat 4 and sleeved on the outer side of the limiting column 54. Then the driving mechanism is turned on. The driving mechanism drives the corresponding two racks 52 to move outward. Since the racks 52 are meshed with the gear columns 53, the racks 52 drive the two adjacent gear columns 53 to rotate. Since the gear columns 53 are meshed with the inner gear ring 5, the gear columns 53 drive the inner gear ring 5 to rotate. During the rotation, the inner gear ring 5 drives the other two gear columns 53 to rotate. The gear columns 53 drive the other two racks 52 to move, so that the four racks 52 move outward synchronously. The rack 52 drives the limiting column 54 to move outward. The limiting column 54 stops moving when it is in close contact with the gear blank 43, thereby achieving the effect of fixing and limiting inner holes of different sizes and improving the cutting accuracy of the gear blank 43.

As shown in Figures 1 to 5, the top of the workbench 1 is rotatably connected to the support seat 4 through a bearing; one end of the rack 52 slides through the support seat 4; four sliding openings 42 are arranged circumferentially on the support seat 4; the limiting columns 54 slide in the corresponding sliding openings 42 respectively; the gear blank 43 is placed on the support seat 4; and a rotating mechanism is provided on one side of the support seat 4.

When in use, the driving mechanism provided by the present invention drives the rack 52 to move by driving the bidirectional ball screw 61 to rotate. Since a ball nut seat is provided at the connection between the bidirectional ball screw 61 and the movable plate 63, the ball nut seat ensures that the movable plate 63 moves in opposite directions. During the movement of the movable plate 63, the movable plate 63 slides on the slide bar 62, and the slide bar 62 limits the movable plate 63 in the horizontal direction. The movable plate 63 drives the rack 52 to move in opposite directions. The tooth columns 53 meshed with the two racks 52 are symmetrical about the center of the circle. When the two racks 52 move in opposite directions, they drive the tooth columns 53 to rotate in the same direction, thereby realizing synchronous movement and rotation.

The cutting device body 36 provided by the present invention is used for cutting processing of the gear blank 43 when in use. The processing size of the gear blank 43 is set in the computer program, and then the electric guide rail 31 and the drive motor 32 are driven to move the cutting device body 36 to the processing position according to the cutting size and the size of the gear blank 43. Then, the electric push rod 35 is started to determine the vertical height of the cutting device body 36, and the cutting device body 36 is opened to cut the gear blank 43.

As shown in Figures 1 and 9, a water tank 7 is fixedly connected to the bottom of the workbench 1; one end of the water tank 7 is connected and fixedly connected to a water pipe 79; one end of the water pipe 79 is installed with a water pump 78; the other end of the water pipe 79 passes through the movable frame 3 and is connected and fixedly connected to the L-shaped plate 34 through a mounting sleeve; one end of the water pipe 79 close to the cutting equipment body 36 is fixedly connected to a nozzle 71; the nozzle 71 is aligned with the center line of the cutting equipment body 36.

When the nozzle 71 provided by the present invention is in use, during the cutting process, the water pump 78 is turned on, and the water pump 78 transports the water in the water tank 7 to the nozzle 71 through the water pipe 79. The water in the nozzle 71 is sprayed on the cutting equipment body 36. On the one hand, the cutting equipment body 36 is cooled to prevent the cutting equipment body 36 from being damaged by too high temperature; on the other hand, it is sprayed on the cutting debris to prevent the cutting debris from splashing and penetrating into the transmission structure and the processing structure, thereby causing the gear blank 43 to deviate and reduce the processing accuracy. By cleaning the debris, the cutting debris and cutting residue are flushed into the annular baffle 2 by the water flow for recycling.

As shown in Figures 3 and 9, a filter plate 72 is fixedly connected to the water tank 7; one end of the filter plate 72 is fixedly connected to a collecting tank 73; a reciprocating screw 75 is rotatably connected between the inner walls of the water tank 7 through a bearing; a scraper 74 is threadedly connected to the outer side of the reciprocating screw 75; the scraper 74 is in contact with the surface of the filter plate 72; a third motor 77 is fixedly connected to the outer side wall of the water tank 7 away from the collecting tank 73; the output shaft of the third motor 77 is fixedly connected to one end of the reciprocating screw 75 through the water tank 7; a movable door is installed on the side wall of the water tank 7 close to the collecting tank 73.

When the scraper 74 provided by the present invention is in use, after cutting a plurality of gear blanks 43, debris and residual materials flow onto the filter plate 72. If the debris and residual materials on the filter plate 72 are not cleaned in time, the filter plate 72 is easily blocked or falls from the filter plate 72 into the water tank 7, making the filter plate 72 ineffective. It is necessary to turn on the third motor 77, and the third motor 77 drives the reciprocating screw 75 to rotate through the output shaft. A ball nut seat is provided at the connection between the reciprocating screw 75 and the scraper 74, and the radial movement of the scraper 74 is ensured by the ball nut seat. The reciprocating screw 75 drives the scraper 74 to move back and forth, and the scraper 74 scrapes the debris and residual materials into the collection tank 73. After a period of time, the movable door is opened to clean the collection tank 73. When the scraper 74 is not in use, it moves to one side of the third motor 77.

Working principle: Different gear blanks 43 have different inner hole diameters during processing. The same gear blank 43 is used in different accessories, and the inner hole diameters may also be different. Inner holes of different sizes may not be directly assembled with the positioning shaft. First, the gear blank 43 is placed on the support seat 4 and sleeved on the outer side of the limit column 54. Then the second motor 68 is turned on. The second motor 68 drives the second rotating wheel 69 to rotate through the output shaft. The second rotating wheel 69 drives the belt 66 to rotate. The belt 66 drives the first belt 66 to rotate. The first belt 66 drives the bidirectional ball screw 61 to rotate. The bidirectional ball screw 61 rotates. Due to the connection between the bidirectional ball screw 61 and the movable plate 63, the A ball nut seat is provided at the joint, and the ball nut seat ensures that the movable plate 63 moves in the opposite direction. During the movement of the movable plate 63, the movable plate 63 slides on the slide bar 62, and the slide bar 62 limits the movable plate 63 in the horizontal direction. The movable plate 63 drives the rack 52 to move in the opposite direction. When the rack 52 is driven to move outward, since the rack 52 is meshed with the tooth column 53, the rack 52 drives the tooth column 53 to rotate. Since the tooth column 53 is meshed with the inner gear ring 5, the tooth column 53 drives the inner gear ring 5 to rotate. During the rotation process of the inner gear ring 5, the other tooth columns 53 are rotated. The tooth column 53 drives the rack 52 to move, and the rack 52 moves outward synchronously. The rack 52 The limiting column 54 is driven to move outward, and the limiting column 54 stops moving when it is in close contact with the gear blank 43, thereby achieving the effect of fixing and limiting the inner holes of different sizes, and improving the cutting accuracy of the gear blank 43; during the cutting process, in order to facilitate the cutting of different positions of the gear blank 43, the first motor 23 is first turned on, and the circular gear 22 is driven to rotate by the first motor 23, and then the outer gear ring 41 is driven to rotate by the circular gear 22. Since the outer gear ring 41 is fixedly connected to the support seat 4, the support seat 4 will drive the fixed gear blank 43 to rotate, thereby achieving the cutting of different positions of the gear blank 43; after cutting a plurality of gear blanks 43, the debris , the residual material flows to the filter plate 72. If the debris and residual material on the filter plate 72 are not cleaned in time, it is easy to clog the filter plate 72 or fall from the filter plate 72 into the water tank 7, making the filter plate 72 ineffective; it is necessary to turn on the third motor 77, and the third motor 77 drives the reciprocating screw 75 to rotate through the output shaft. A ball nut seat is provided at the connection between the reciprocating screw 75 and the scraper 74, and the ball nut seat ensures the radial movement of the scraper 74. The reciprocating screw 75 drives the scraper 74 to move back and forth, and the scraper 74 scrapes the debris and residual material into the collection tank 73. After a period of time, the movable door is opened to clean the collection tank 73; when the scraper 74 is not in use, it is moved to one side of the third motor 77.
